Abstract

The utility model relates to a polyurethane composite wear-resistant pump which comprises a pump case, an impeller, a front fender and a back fender. The utility model is characterized in that a polyurethane layer is compounded on each of the work surfaces of the pump case, the impeller, the front fender and the back fender. The polyurethane composite wear-resistant pump has the structure that the main wear working surfaces of flow passage components of a wear-resistant pump are made of super wear-resistant polyurethane materials, while the non-working parts use common irons or ordinary steel components which have low cost as frameworks, and the wear-resistant polyurethane is compounded on the common irons or the steel components. The utility model gives full play to the properties of wear-resistance and corrosion prevention of polyurethane, ensures that metal inner materials are easy for processing and shaping, and has the advantages of low cost, favorable sealing performance, light weight, low working noise, low energy consumption and convenient installation and maintenance.

Description

The polyurethane composite anti-wear pump

Technical field

The utility model relates to machinery such as metallurgy, mine, specifically polyurethane composite anti-wear pump.

Background technique

Wear pump in the industrial pump is the visual plant that is widely used in departments such as metallurgy, mine, electric power, chemical industry, coal, oil, light industry, building materials and river course mediation, urban sewage.Because operating conditions is abominable, working life is all very short, and a large amount of high alloy materials have not only been wasted in the premature wear of its flow passage components and corrosion, and it still is a kind of highly energy-consuming product.

Existing wear pump flow passage components are owing to the restriction of processing technology, and it is an integral body that its groundwork wear surface and non-working surface, skeleton all adopt single material, and material is many based on abrasion resistance alloy.Wear pump is a kind of product of highly energy-consuming, and the product percent of pass of producing is low, and the fine finishing difficulty is big, the usability instability, and poor sealing performance, Heavy Weight, energy consumption was big when running was used, noise big, safeguard that labor intensity is big.

Summary of the invention

The purpose of this utility model provides a kind of both wear-resisting erosion resistances, the polyurethane composite anti-wear pump that machine shaping is simple again, cost is low.

The utility model pin is tied the variety of issue that existing wear pump flow passage components exist, through researching and developing out for many years the polyurethane composite anti-wear pump of new structure.Concrete scheme is: the utility model comprises pump case, impeller, apron plate and back backplate, it is characterized in that compound one deck polyurethane layer on the working surface of pump case, impeller, apron plate and back backplate.

Polyurethane material is the high-abrasive material of generally acknowledging in the existing organic and inorganic material, the polyurethane composite anti-wear pump adopts super wear-resisting polyurethane material at the wear pump flow passage components working surface that mainly weares and teares, and the position of inoperative adopts cheaply plain cast iron or plain carbon steel member as skeleton, is compound on plain cast iron or the steel member by wear-resisting polyurethane.Both given full play to the wear-resisting erosion resistance performance of polyurethane on the structure, and made that again material machine shaping was simple in the metal, cost is low, and good airproof performance, in light weight, operating noise is little, energy consumption is low, convenient for installation and maintenance.
